Abstract (en)
[origin: EP0676721A2] A styled vector generator (210) within a graphics controller device that works in parallel with a traditional solid vector generator (208) to create a repeating styled vector pattern. Before the pixels are transmitted to the frame buffer by the solid vector generator, the styled vector generator (210) paints each pixel in the pixel stream into either the foreground color (224) or the background color (222), depending on the pattern. The color for each pixel is determined by counting through the pixels in each segment (212, 214) of the pattern, moving from segment to segment. The pattern is defined by the lengths of individual segments, and the number of segments that make up the pattern. The styled vector generator also accepts an offset (304, 308) within the pattern to start rendering the pattern. <IMAGE>
